Abstract:Intelligent natural resource supervision is an important direction of current natural resource informatization construction. The development of an integrated monitoring system based on remote sensing satellite dynamic monitoring, UAV aerial survey, video monitoring, mobile internet, Internet of things, intellisense, and big data analysis applications provide a technical basis for the construction of an intelligent supervision system. Taking cultivated land protection law enforcement supervision platform in Rizhao city in Shandong province as an example, application of intelligent monitoring system of the space-air-ground integrated system in the supervision of natural resources has been studied. It will improve the work efficiency of cultivated land protection monitoring and supervision, and provide intelligent and scientific service for decision-making.
